Not even 24 hours after spy shots of the next-generation Lexus GS emerged, we have some photos of a similarly taped up IS driving around Germany:

There’s even fewer details revealed in these shots, other than that the rear bumper has been cut and stretched, likely to make the shell fit over the new platform that’s expected to be shared between the IS & GS models.

Even with a new mule out and about, there’s very little reason to think the next-generation IS is right around the corner — especially with the revised edition introduced this year. My own guess would be the next-generation IS debuts in 2012 as a 2013 model.
